Frequently Asked Questions

What is the Operating Expense Ratio (OER)?
OER is a metric comparing operating costs against gross revenues. A lower OER indicates a highly efficient business that converts a larger portion of revenue into net operating income.
How do fixed operating costs differ from variable operating costs?
Fixed operating costs (e.g., rent, salaries) remain static regardless of production levels. Variable operating costs (e.g., raw materials, packaging) scale directly with production volumes.
